I have a 3 site network A, B, and C. Each site has its own DC, that replicates to the others. Each site also has a local NAS (Thecus) device. The NAS devices should be accessible from every other site.
I'm having an issue where the NAS device at site A cannot be reached from A's DC, but every other machine everywhere else(and with any login account) can reach the shares.
From site A's DC, we can ping that NAS device and we can browse to the admin page.
My thought, is there must be some type of group policy restricting that machine from accessing that NAS device. I say the machine, because the login account can access it from the same site, on different machines, and from other sites as well. If we use another login on site A's DC, we still cannot browse to the share.
Where is this type of restriction defined in group policy? I haven't had a whole lot of experience with group policy.
I guess I forgot about an error we had received in the event logs. It's error 5722: "The session setup from the computer failed to authenticate. The name of the account referenced in the security database is . The following error occurred: Access is Denied.
